The plane, carrying President Felix Tshisekedi’s driver, a logistics manager and some soldiers, was headed from Goma to the capital Kinshasa and went off radar on Thursday afternoon, an hour after departing, a statement from the civil aviation authority said.

Debris of the plane has been found but the passengers are still missing, said adviser Vidiye Tshimanga. He had told Reuters earlier on Friday that eight bodies had been found but said that information was incorrect.

The cause of the accident was not yet clear.

Local media showed a crowd of hundreds of Tshisekedi supporters hitting the streets of Kinshasa after the news broke on Friday morning, fearing that the plane crash had been some kind of failed coup attempt against Tshisekedi. The president took over from long-standing former President Joseph Kabila this year.

No information immediately backed up such a claim. (Reporting By Stanis Bujakera and Djaffar Al-Katanty Writing by Edward McAllister and Anna Pujol-Mazzini; Editing by Andrew Heavens and Frances Kerry)
